WILDLIFE IN FOCUS

with ecologist Sue StevensDo you know the difference between a
Magpie, Crow, Raven and Currawong?

﻿﻿Good or bad, this bird will probably
visit your garden.

If you like the smaller birds in
your garden, it may be timely for you to get to recognise the difference
because one of them is considered a nest predator, and is partly responsible
for the decline of smaller species in some areas where it lives.

Let’s find out more about this bird.

Currawongs now remain in cities all year round, mainly
because there’s plenty of food around-cat food, dog food, bird feeders, you
name it.

They’re a pretty smart bird so don’t
let them train you into thinking that you need to feed them.

As Sue mentions quite regularly,
what we feed birds is largely lacking in nutrients that they really need and in
this case, the Currawong includes smaller birds in their diet.

Plus you don’t want a nest of
Currawongs in your backyard, because during breeding season, pairs defend the
nest-site and surrounding territory where they find food for their young.

But if you don’t have small birds in
your garden you might just think the birds were great to have around as they
eat carrion, rodents, and insects - keeping the local area clean and tidy.

If you have any questions about your
Pied Currawongs or a photo, send it in to realworldgardener@gmail.com or write in to 2RRR P.O. Box 644 Gladesville

VEGETABLE HEROES

Today’s vegetable or fruit hero is not really a fruit and it's Strawberries or Fragaria x ananasa.

Did you know that Fragaria means fragrance in Latin?Strawberries aren’t actually berries
because true berries have seeds inside them.

And as every schoolkid will tell
you, strawberries have seeds on the outside, and usually about 200 of them!

So what are strawberries exactly?

Did you know that Strawberries are
sometimes called an accessory fruit or false fruit because of the seeds being
on the outside?

Here’s a botanical bite.

Fruit usually grows from the ovary
of the flower, but in the strawberries case, some or all of the fruit grows on
outside of the ovary.

That part of the flower that holds
the ovary is called the receptacle.

You might find it hard to imagine,
but each little "seed" (achene) on the outside of the strawberry fruit
is actually one of the ovaries of the flower, with a seed inside it. Strange
isn’t it?

Fragaria vescaor the Alpine strawberry is native throughout
the Northern Hemisphere.

Botanists think this was probably
the ancestor of the garden strawberry of today.

Would you believe that there’s archaeological
evidence suggesting that people ate strawberries as far back as during the
Stone Age?

The first people to grow
strawberries as a crop were the Persians in ancient Persia.

The Persian-called their strawberry
plants - Toot Farangi.

By the 18th century Fragaria x ananassa had replaced the
alpine strawberry because of the larger berry or fruit.

When to grow?It’s probably not the right time of
year to grow plant out strawberries in many districts, but if you see them for
sale as potted strawberries, because you surely will, you can plant them out in
January.

For all sub-tropical, temperate and
arid zones you can plant strawberries now, but you’ll get advice that May and
June are the best planting times.

For cool mountain districts, October
and November are your best planting times.

They’re frost sensitive but a 10cm
layer of mulch will be enough to protect the plants.

So what are the strawberry plants’ requirements?

Strawberries are short-lived
herbaceous perennials, meaning plants can produce for 2-3 years.

Did you know that commercially
strawberries are grown for only one season and replanted each year to keep up
the yield levels?

The pattern for most strawberries is
flowering in spring, set fruit in late spring/early summer, send runners out in
summer and become dormant in winter.

At this time of year you will be
able to get the ever bearing varieties which give you a second crop in autumn.

If you planted your strawberry
plants, in last autumn and winter, they should’ve flowered already and you’ll
be telling me that you’ve been enjoying strawberries with cream already.

But why not plant some more plants
for Autumn strawberries?

What do Strawberry plants really love?

Not sure what they like?
Well…Strawberries love at least 6 hours of sun a day and will grow in most
soils but strawberries prefer a sandy loam that is deep and contains a lot of
organic matter.

IMPORTANT: When
planting a strawberry plant, make sure that about a third of the crown is above
the soil. If you plant too deep or shallow the plant might die.

Strawberries have 70% of their roots
located in the top 8cm of soil.

By mulching the soil, it helps to
keep the roots from drying out and will prevent the plant from drowning in
boggy soil.

This means that if growing your
strawberries in the garden, you need to grow them on mounds toimprove drainage and you will also need to
put down a thick layer of mulch such as hay, pea straw or sugar cane to prevent
the berries from touching the soil and rotting.

Mulch as you should now, also
prevents the soil from drying out too much.

The idea behind strawberry pots is good in principle but in practise I find it needs careful attention because the plants dry out too much.

Potting soils usually have the right
mix if you’re planning on planting strawberries in a container.

but

I would also recommend adding some
coco peat into the potting mix to increase water holding capacity.

And you know strawberry pots have
several holes in them to cater for about5-6 plants.

TIP:
Attaching your pots to a dripper system and putting a saucer under the
strawberry pot will save your strawberry crop this year.

Also make sure you water the plants,
especially when the young plants are establishing, and during dry spells.

TIP:Make sure your berries are fully
red before picking them because they don't get any riper off the vine.

Cut the stem above the berry with scissors.

Over summer, strawberry plants send out runners. These modified shoots
can be used to propagate new plants but if you don't need new plants, cut these
runners off.

After fruiting has finished, tidy up the bushes by giving them a hard
prune down to 10cm.

Stick 'em in the fridge soon afterpicking the strawberries and don't wash the strawberries until just
before you want to eat them.

Strawberries don't last, and the extra water on them causes their cells
to break down more quickly.

TIP: Wash the berries and pat them dry before removing the stems. That
way you avoid excess water entering the berries from the stem end.

Use the berries within three or four days.

To really feed a family you need
about 20-30 plants to provide plenty of fruit, but even a couple of plants can
be fun to grow.

Which Strawberries to plant now?

For Ever- bearing varieties, the autumn crop is the biggest and you can
choose from Tempation which doesn't
send out runners so it's great for hanging baskets and Sweetheart is very sweet to taste – an everlasting variety also
have their fruit set in autumn.

Why are they good for you?

Growing your own strawberries is
much healthier because strawberries are ranked third out of 50 popular fruits
and vegetables that retain pesticide residues.

From only half a punnet of
strawberries you'll get more than 100% of your daily needs of Vitamin C,and5.5g fibre in if you eat the whole punnet of strawberries that's about 20% of your daily fibre needs.

Did you know that eating
strawberries, which are rich in nitrate, can increase the flow of blood &
oxygen to the muscles by 7%?

This prevents muscle fatigue, making
exercise easier.

Strawberries are also low in
kilojoules, meaning you can eat 2 cups as one of your daily fruit serves!

DESIGN ELEMENTS

What it isn’t, is a garden theme or
style because they’re clearly defined.

A garden theme is best explained by using examples like, a blue and white garden, a conifer garden fern, or Chinese garden. Garden style is formal, informal, contemporary, modernist, gardenesque and so on. Let’s find out about concept
gardens.

Next time to see garden makeovers or show gardens you’ll know not to copy them judiciously because it does involve a bit of smoke and mirrors to make it look spectacular.

The number one aspect is that plants are planted closely to make them look lush, but don’t do that in your garden, because they’ll crowd each other out and the whole design will start looking a mess.

PLANT OF THE WEEK

with Karen Smith hort journal editor www.hortjournal.com.auAfter mosses and algae, the first land plants on earth were
ferns.

Did you know that fern fossils of a group of now extinct
ferns called Glossopteris can be found in various parts of Australia still
today and these will be in the order of 200 million years old.

What’s that got to do with
plant of the week?

Nothing really other than
it’s a fern and the foliage looks like a cross between a tree fern and a cycad.

Let’s find out about this
plant.

Blechnum
ferns grow in conditions that if you already grow ferns you would go ah yes-
humid, cool but not cold, and filtered light as you would find under evergreen
trees.

Given the
right conditions indoors or out, blechnum ferns can be lovely ferns that will
round out your fern collection.

Blechnum ferns...”Silver
lady”

Silver Lady is a
form of Blechnum gibbum, and is a dwarf tree fern. Silver Lady’s
is a fast grower and great for those shady parts of the garden.

Silver Lady has a
spread of around a metre, you need a size of pot diameter of around 40cm,
planting up from a 15cm-20cm pot size.

Silver
Lady looks good when multi-planted for that tropical feel to the
garden.

In general, Blechnum
ferns do best in moist, free-draining, compost-enriched and slightly acidic
soil in a shady location.
